Which phrase describes the motion and attractive forces of ideal gas particles?

Answer is: random straight-line motion and no attractive forces.

An ideal gas is:

1) made up of molecules which are in constant random motion in straight lines.

2) all collisions are perfectly elastic, there is no loss of kinetic energy during the collision.

3) follows ideal gas law: p·V = n·R·T.

4) the gas particles have negligible volume.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

pv=nrt
